The rice plant (Oryza sativa) as one of the most important (gluten free) sorts of cereals forms the nutritional basis in many parts of the world.

The main production area for rice is in Asia. Here, more than 95% of global yields are harvested. The main growing regions for rice in Europe are northern Italy, southern France, Spain and Portugal.

80% of the world's rice harvest is generated in wet rice cultivation.
Concerning the types of rice, a distinction between long grain rice (Indica) and short-grain rice (Japonica) can be established.

For the milling process from rice to rice semolina, it is short grain rice which is almost exclusively used. Long grain rice is to a large extent processed into parboiled rice.
